New Wireless RC 31.1.6 - Lots of Fixes

[Mloraditch]

Lots of Bug Fixes, several having to do with Radius that sound suspiciously like random forum posts I've seen!

EDIT: "Sporadic packet loss & instability on Layer 3 roaming & Teleworker VPN SSID's (Wi-Fi 6, Wi-Fi 6E APs)" was moved to fixes by Meraki after the original post. Very very long outstanding bug that may finally be fixed.

Important note

• Wi-Fi 5 Wave 2 MRs support - This version and subsequent MR 31.x.x are only supported on 802.11ax (Wi-Fi 6) and newer MR models. 802.11ac Wave 2 and older products will only upgrade to the backup version (MR 30.7.1) if they are in networks configured for MR 31.x.x versions, and thus, the new features will not be available. The bug fixes listed below will also not apply to Wi-Fi 5 Wave 2 and older MRs. (https://documentation.meraki.com/MR/Other_Topics/Cisco_Meraki_MR_Firmware_Restrictions_Overview_and_...)
• Includes support for Wi-Fi7 APs (https://documentation.meraki.com/MR/MR_Overview_and_Specifications/CW9176I_%2F%2F_CW9176D1_Datasheet, https://documentation.meraki.com/MR/MR_Overview_and_Specifications/CW9178_Datasheet)

Bug fixes

• General stability and performance improvements
• MR56 ethernet port flaps occur when connected to C9300-48UN(V04) at 5Gbps speeds
• MR57 ethernet port flaps occur when connected to MS355 at 5Gbps speeds
• MR46 not responding to Probe Requests from clients
• Channel & power not configurable via LSP on CW9163E APs
• Wildcard NAS-IPv6-Address AVP sent on config change (Wi-Fi 6, Wi-Fi 6E APs)
• NAS-IP-Address discarded (Wi-Fi 6, Wi-Fi 6E APs)
• RADSec authentication failures (Wi-Fi 6, Wi-Fi 6E APs)
• DHCP offer is not forwarded if broadcast flag is set (Wi-Fi 7 APs)
• mDNS traffic blocked (Wi-Fi 7 APs)
• SSIDs broadcast on 6Ghz despite being disabled when using WPA3 transition mode (Wi-Fi 7 APs)

Most important part : 802.11ac Wave 2 and older products will only upgrade to the backup version (MR 30.7.1)

😍

[RWelch]

Exactly ( ↖️ ) 🎉

[Paccers]

@cmrin shambles after being beaten to the release notes post 😏

[cmr]

Just sharing the love @Paccers 👍

[Paccers]

For me the 'Sporadic packet loss & instability on Layer 3 roaming & Teleworker VPN SSID's (Wi-Fi 6, Wi-Fi 6E APs)' item is listed under 'Bug Fixes' section

[RaphaelL]

Same here but I swear it was listed as a known issue. Might be a corrected typo

[Mloraditch]

Yes i see that now too. I definitely just copied and pasted so they must have edited. Crazy if that's finally fixed

[meraki-chris]

Yes, that was a correction - moved to bug fixes

[RWelch]

@meraki-chris 👏 👏 👏 🎉

I perfromed a rollback on my MR36H to MR 30.7.1. As posted already with MR 31.1.5.x, I also experience lags with MR 31.1.6 during longer Webex Calls (>30 minutes) and other usage like streams or "high" bandwidth and low latency connections. After 50 minutes call today, I even got a short loss of connectivity. With MR 30.7.1, at least with my MR36H in use, I have no issues. Someone else epxerience lags with MR36(H) and MR 31.x?

[NolanHerring]

Were you able to get anywhere with support?  I just upgraded a site to 31.1.5.1 2 weeks ago and been having issues, and was planning on upgraded to 31.1.6 but seems like I might be better off just going back to 30.7.1

Site has a mixture of MR42/MR46E/MR44. Since the upgrade the site has been complaining (everywhere) about slow connections, random disconnects, trouble connecting. 

[lotsofdots]

I only posted my question in this forum. I did not raise a support request. But no update to my question in the community post yet.

I downgraded to 30.7.1 and have no issues with the MR36H. With 31.1.6 or the earlier 31.1.5.x release I have had the issues you described, too.

[lotsofdots]

I am now with the MR 31.1.7 release on my MR36H for one week. So far, everything is working, at least for my environment. I did not get the issues I had with earlier versions after 30.7.1.  

[Paccers]

This was promoted to Stable as of yesterday (15 days!), record time for Stable RC to Stable move?

[NolanHerring]

So 31.1.6 at a site with a mixture of MR44/MR42/MR42E/MR46E and this upgrade has introduced tons of issues. Wi-Fi Calling refuses to work on MR44 models, but works fine on MR42. PCAPs provided to support for the case I have open (tons of TCP retransmissions). Slack messages fail to send/load etc. Reverting back to 30.7.1 for now, but I currently have no faith in the 31.X train.

What's the general consensus on this version ?  I'm running 31.1.5.1, is it worth the upgrade now or wait for the next version?
Have noted @NolanHerring 's issues, last thing I want is a big dollop of unnecessary pain for no useful new features or bug fixes

[NolanHerring]

As an update we rolled back to 30.7.1 three-weeks ago, and everything has been stable since. I did just see there is a new version 31.1.7 with lots of 'bug fixes'. Potentially fixes for what we were running into but I personally don't really feel like having to impact the business just to test and validate that, so I'll be sitting on 30.7.1 for a while.

Bug Fixes:

• General stability and performance improvements
• False positive DFS alerts in Japan on MR56 APs
• APs stop transmitting on wired interfaces due to exception (Wi-Fi 6 APs)
• Clients disconnect with error code 17 (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)
• Clients disconnect with reason code 0 (reserved) (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)
• Association ID mismatch (Wi-Fi 6, Wi-Fi 6E, Wi-Fi 7 APs)
• 2.4GHz 802.11n clients unable to connect (Wi-Fi 7 APs)

@NolanHerring We moved to 31.1.7 a week ago, 500+ AP's, MR33/36/44's - all seems OK so far
